A mechanical interlock mechanism described herein prevents a user from removing a memory card while a portable electronic device is connected to an external power supply. The portable electronic device includes a memory port, a power connector, and a cover. The cover is movable between first and second positions. In the first position, the cover exposes the memory port. In the second position, the cover exposes the power connector and at least partially blocks the memory port and any memory card inserted in the memory port. Thus, the second position prevents the user from removing a memory card from the memory port while an external power supply is connected to the power connector.

An express card adapted to receive and utilize a SIM card that can be electrically coupled with a computer is disclosed. The express card includes an extended portion with a printed circuit board (PCB) and a SIM card connector for coupling a SIM card with the PCB. An external antenna jack is electrically coupled with the PCB extended portion. An antenna/SIM card support structure is mounted on the PCB extended portion covering the SIM card connector. The antenna/SIM. card support structure forms a slot adapted to receive and seat a SIM card and form an electrical connection between the SIM card and the SIM card connector. A metallic flex antenna can be affixed to the antenna/SIM card support structure such that the antenna characteristics of an external antenna can be affected based on the metallization pattern and placement of the metallic flex antenna.

A cord retraction assembly for an electronic device includes a reel for winding and retracting the cord, a catch element adapted to engage the reel to prevent retraction of the cord, and an interlock for disabling the catch element when the cord is wound unto the reel. The catch element is urged into engagement with the reel by a spring to prevent retraction of the cord during use. A release button disengages the catch element from the reel, allowing the cord to retract. The interlock comprises a pivotally-mounted arm that rides over the cord as the cord accumulates on the reel. The accumulation of the cord on the reel pushes the arm outward into engagement with the catch element so as to prevent the catch element from moving back to the engaged position. As the cord is unwound from the reel, the catch element is able to return to the engaged position.
摘要:
A radiotelephone having a slidably retractable member with an acoustic duct for transmitting sound through the member into a microphone housed in the radiotelephone's main body. The member is slidable to an extended position for use such that a sound inlet of the acoustic duct is exposed for collecting sound as a person speaks into it. Sound travels through the acoustic duct and passes directly through a sound outlet into the microphone. A sealing member adjacent the microphone acoustically seals the sound outlet to a sound port in the microphone. Features are provided on the slidable member and main body for guiding the member into its retracted and extended positions. Also, detent features hold the member in its two positions. In one embodiment, the member covers an external face of the radiotelephone when retracted. In another embodiment, the member is housed within the main body of the radiotelephone, and a portion of the sound inlet is adjacent the microphone in the retracted position for use without extending the member.

A backlit keypad assembly includes a flexible film having a bottom surface having electrical circuits, typically referred to as flex circuits, thereon and a top surface having at least one, and preferably a plurality of keys defined thereon. Each backlit key includes a cavity on the underside thereof. In each cavity is a light emitting diode, preferably of bottom emitting type, attached to the flexible film and connected to the electrical circuits and a filler material which at least partially surrounds the light emitting diode. Associated with each key is a push-type switch below and in respective aligned relationship with the light emitting diodes which senses when the corresponding key is pressed down by a user. The light emitting diodes emit light directly through the flexible film without intervening layers such as light guides, thereby allowing the overall lighted keypad assembly to be thinner than with previous approaches. Such a keypad may be fabricated by directly attaching a plurality of bottom emitting light emitting diodes to the bottom side of the flexible film and connecting the light emitting diodes to the electrical circuits. Thereafter, the flexible film is vacuum formed so as to form a plurality of depressible keys on the top surface thereof and a corresponding plurality of cavities on the bottom surface thereof containing therein the light emitting diodes. The process continues by thereafter substantially filling the remainder of the cavities with a filler material which hardens upon curing and adheres to the bottom surface of the flexible film so as to form a flexible pad. The flexible pad is then typically placed in intimate contact with the printed circuit board and preferably mated thereto.
